EQUILIBRIUM END-VALVE.

To all-whom it may concern:

Be it known that I, J OHANN KOENIG, eng n'eer, a subject of the King of Bavaria, residing at 97 Alexanderstrasse, Riga, Russia, have invented new and useful Improvements m Equilibrium Stop-Valves, of which the following is a specification. l

The subject of my invention is a stopv'alve, whose valve-body comprises two telescopic cylindrical members, making a tight joint with each other. The one member is stationary, while the other, which is provlded with a seating-face, can slide by being connected to the valve-stem by means of a lever device. The sliding member is furnished with apertures to admit the steam or other fluid to the interior of the valve-body, for the purpose of balancing the valve.

According to my invention not only is the valve balanced, but free in and out-flow of the steamer liquid without shocks is insured, and there is no obstruction of the passage of flow by the actuating device.

Two forms of construction of the new valve are illustrat d in the accompanying Figure 1 is alongitudinal'section through the one construction. Fig. 2v is a cross section on the line A-B of Fig. 1. Fig. 3 is a longitudinal section through a modification. fig. 4 is a cross section on the line AB of In Figs. 1 and 2, a bis the casing contain-'- ing the valve-body. The latter comprises parts 0 (l, the exterior ends being conical, so that no detrimental obstruction'is offered to the inand out-flowing current of steam or liquid. The exterior part c is'integral with the easing a, while the interior part cl slides within the part c. This part d is furnished with a ring 2 presentinga seating-face 7, adapted, on the valve being closed, to make a tight joint with the seat 6 of the casing-part b. The part d butts against a plate 1', p being packing material between the two. From the plate 1" there projects the rod 8, and the rod and plate are secured to the part d. by

rod and screwed into the plate 1' and part all. The rod 8 presents an eye 0 and into this there takes the longer arm of a bent'lever m, pivoted by a pin 00 to the lugs ypendent from the cover of the casing a. The shorter lever-arm has a forked end which embraces Specification of mm latent. Application amber 8, 1905. Serial No. 456,442.

y turning the handwheel h, the part d of the valve-body. can obviously be approached to or retracted from the seat e of the casingpart b, as desired. In this manner the valvepassage can be adjusted as required, or the valve wholly closed or opened. The part at is perforated at 2', j and the plate 1' at is, so

that the steam or liquid can flow' through the apertures to the chamber 0 of whereby the valve is balanced.

In the modification shown in Figs. 3 and 4 the arrangement illustrated in Figs. 1 and 2 is reversed, the inner part a being here stationary while the outer part (1. slides. p is packing located between the part a and the. plater'. In this modification the outer part 03 presents a seating-face f, adapted to thecasing,

-make a tight joint with the seat e of the part a of the casing a b. The valve actuating parts m g ii are substantially the same as in the construction illustrated in Figs. 1 l and 2, the longer lever arm, however, being pivoted to the sliding part d by means of a link 8'. To insure balancing ofthe valve the parts 0 d are provided with apertures z" and the plate 1' furnished Wltll an aper-- ture is.

Having thus described my invention, I declare that what I claim is 1. An equilibrium stop valve for pipe conduits, comprising a valve casing, and a relievin casing firmly connected with and place in the said valve casing and concentrically arranged around the pipe axis with a concentric annular space for the flow of the fluid therebetween, a slidably arranged valve-cone on the exterior of said relieving casing, whose movement axis coincideswith the pipe axis and an angle lever for giving 2. An equilibrium stop valve for pipe conduits, comprisin a valve casing, and a relievin casing rmly ;connected with and place in the said valve casing and concentrically arranged around the pipe axis with a concentric annular space for the flow of the fluid therebetween, a slidably arranged valve-cone on the. exterior of said relieving casing, whose movement axis coincides-with the pipe axis and an angle lever for givmg movement to-said valve-cone, said valve casing, relieving casing and valve-cone having such shape that the passage therebetween' causes only gradual alterations in speed as forated well as in the direction of flow of the fluid, lever pivoted to the wall of the casing out so that the flowing resistance is reduced to the smallest possible degree.

3. An equllibrium stop valve comprising a casing with valve seat, a stationary cylindrical member located in the casing, a percylindrical member telescoping therewith and having communication with the interior thereof and having a seating face fitted'to said valve seat, a screw stem passed through the wall of the casing, a bent side the fluid-passage and having its arms jointed respectively to said stem and telescoping member.

In witness whereof I have hereunto signed my name this 23rd day of September 1908, in the presence of two subscribing witnesses.
